Doktor vs Arzt
Difference between Doktor and Arzt/Ärztin
I think the difference is the academic title. Not every "Arzt" (medical doctor) has an academic title. ...A normal "Arzt" is not a "Doktor".
Edit: But only in relation to the title. Both of them are doctors (Ärzte).
Could it be the same as in English? A doctor is a very broad academic term, like the other person said it is a title, (highest academic achievement) in a variety of disciplines e.g a doctor of literature, a doctor of philosophy, psychology, engineering (also medicine) whilst an Artzt is very specific, that is a medical doctor. I think all medical doctors also have doctorates so they can use the title Doktor also?
Doctor is not the highest academic title. The professor is higher than the doctor.
Edit: No, not all medical doctors have the academic title "Dr." (doctor).
Hey good question my father is a doctor but lol; a doctor of machines. Hah. He doesn't like 'Doctor' on his airplane tickets cause he doesn't want to be called to an emergency lol.
Please have a look at this site: https://de.m.wikipedia.org/wiki/Doktor_der_Medizin
Ok, gSY etc, point taken, not all doctors have doctorates. It appears that you can be a medical doctor, but without having a doctorate and so without the academic title 'Dr.'. So this would be an Artzt? So why does my local Artzt or GP (General Practitioner) or MD (medical doctor) call themselves 'Dr. Smith'? Obviously only medical doctors (and dentists?) can use the title Dr' without having a doctorate, all others who call themselves doctors have to have a doctorate degree/PhD? (BTW in my earlier comment I should have said 'highest academic degree', not 'highest academic achievement', my mistake).
When speaking they are "Dr. Smith", but likely on stationary, etc. they would be called " Firstname Smith, MD".
A normal medical doctor has to write a thesis to obtain his doctoral degree (doctorate = doctoral degree).
But I think it makes no difference in the daily life. Most people say doctor.
So an Arzt is sometimes called a doctor by just people. So I come into an examination 'Guten Tag Doktor, Wie geht's dir heute?'. Even if he is officially an Arzt?
